Parametric Optimization of Process Parameters of EDM for SS304 by Using Design of Experiments Method

Narendra Kumar Patel | Harshwardhan Singh Rathore

Abstract: EDM has become an important and cost-effective method of machining extremely tough and brittle electrically conductive materials. It is widely used in the process of making moulds and dies and sections of complex geometry and intricate shapes. The work-piece material has been selected for this experiment is AISI304 Stainless steel taking into account its wide usage in industrial applications. In todays world 304 Stainless steel contributes to almost half of the worlds production and consumption for industrial purposes. The input variable parameters are discharge current, pulse on time and pulse off time. Taguchi method is applied to create an L18 orthogonal array of input variables using the Design of Experiments (DOE). The effect of the variable parameters mentioned above upon machining characteristics such as Material Removal Rate (MRR), will be carried out for optimization and investigation. The tool material will be chosen as copper electrode whose shape and size is cylindrical bar of 10 mm diameter. And the work-piece material is 5mm thick 304 stainless steel plate.
